Mathematical Reasoning: Writing and Proof

Written by: Ted Sundstrom (Grand Valley University)

Dozens of colleges and universities have adopted this free, online mathematics textbook for their courses. Students from coast to coast and even in Bangladesh have been assigned this text while studying the process of constructing and writing proofs. It was written by Ted Sundstrom of Grand Valley University and there are even over 100 screencasts on YouTube to supplement the text.

Along with the text and screencasts, the website for this free textbook includes study guides and a short guide on writing mathematical proofs. This mathematical reasoning textbook is great for self-study as the author has provided an answer-key for selected problems and even indicates which questions have answers within the text.

When I last visited, the textbook was last updated on November 7, 2016 and labeled as version 2.1.
